WARNING:
To minimize risk of severe injury in the
event of a collision or a sudden stop, both
the driver and passenger seatbacks should
always be in an upright position while the
vehicle is in motion. The protection pro-
vided by the seat belts and airbags may be
reduced significantly when the seatbacks
are reclined. There is greater risk that the
driver and passenger will slide under the
seat belt which may result in serious injury
if a crash occurs when the seatbacks are
reclined.
The seat belt cannot provide full protection
to an occupant if the seat back is reclined.
!
B080D02JM-AATAdjustable HeadrestsHeadrests are designed to help reduce the risk
of neck injuries.
To raise the headrest, pull it up. To lower it, push
it down while pressing the lock knob. To remove
the headrest, raise it as far as it can go then
press the lock knob while pulling upward. This
should only be done when the seat is not
occupied.
WARNING:
o For maximum effectiveness in case of an
accident the headrest should be ad-
justed so the middle of the headrest is at
the same height as the top of the
occupant's eyes. For this reason, the
use of a cushion that holds the body
away from the seatback is not recom-
mended.
o Do not operate the vehicle with the head-
rests removed as injury to the occupants
may occur in the event of an accident.
Headrests may provide protection against
neck injuries when properly adjusted.
o Do not adjust the headrest height while
the vehicle is in motion.

B083D01NF-AATActive Headrests (If Installed)The active headrest is designed to move for-
ward and upward during a rear impact. This
helps to prevent the driver's and front
passenger's head from moving backward and
thus helps prevent neck injuries.

different positions by pulling the headrest for-
ward. To adjust the headrest rearward, pull it
fully forward to the farthest position and release
it. Adjust the headrest so that it properly sup-
ports the head and neck.
